Oil & Fuel Synthetic motor oil

[massey4mike]

I recently bought a 2005 M6800 and it will see considerable use this winter in Northern NH. I want to use synthetic motor oil to hasten lubrication in near zero temperatures. I found the Kubota USA lubricant schedule very confusing as it says nothing about the engine type in the M6800 but states that if there is no EGR then do not use API CJ-4 oil. The owner's manual I have is for a 2002 and states that API CF oil should be used. Mobil 1 Extended Performance oil says that it meets CF rating but the container clearly states "for gasoline engines". Can/should I use this oil as it is NOT CJ-4 rated and all the diesel synthetics are.

Use Valvoline SynPower. It is CF rated for gasoline AND diesel engines. I use it because the BX24 calls for 10W-30 CF rated.

Valvoline Premium Blue is good stuff.

Or, Shell Rotella 5w-40 synthetic. Just another option.

Or Mobil1 Turbo Diesel Truck 5-40. That is what I use. (they have the 5 gallon containers at Walmart)
Mobil 1 Turbo Diesel Truck 5W-40

Mobil Delvac 1 is also good but hard to find.

I would never use Mobil again, I used for years until I called there CS..They are rude and do not know much.. I switched to another oil place.

Are you sure about that?
What dose the 5 Gallon bucket look like?

The problem with Mobil 1 Diesel Truck and the Shell Rotella Synthetic is that they are both CJ-4 rated and Kubota's Lubricant Schedule states not to use that in engines that do not have EGR. I have not seen any of the other oils listed here, they must be in specific parts stores? I just need to know if the CF rating on the Mobil 1 Extended Performance means that it is suitable for my diesel engine. Does anyone know if that is the case?

At your Kubota dealer, they sell 10w-30, their own label. That would be what most guys use up here in Northern Michigan for cold weather starts. That's not quite as low a flow rate as you would like, but the best Kubota can do as they don't sell a 5w-X oil, AFAIK.

If you are wondering whether you could/should use that specific Mobil-1 in your tractor, then just call your dealer and ask him!!! Would he not give you a straight answer? Call Messick or Barlows, if he won't.

Finally this. Your manual is out of date. Likely printed off materials from 2003 or 2004. Times change, recommendations change and those old printed manuals can throw you a bum steer.

Here is a quote from another thread on this subject.
"I contacted Kubota this summer with the same question. If you do a search, you will see that I was told CJ-4 oils are perfectly fine for your diesel tractors. Kubota has not updated their manuals or web site to reflect the change. I was told it is just a matter of time (slow moving corporate issues) before this happens. CJ-4 is the newest spec. for diesel rated oils and is compatible with LSD and ULSD fuels. The oil change intervel is still the same. This really is no longer an issue and you should not be concerned about it. You will see that within a year ALL diesel oils will be a CJ-4 spec. CI spec oil is still avaiable but will shortly be out of stock since the CJ-4 spec replaces it.
I'm sure some will disagree with me, and that's fine. I did my homework and will stick with what the Kubota engineer told me over the phone.
We also discussed viscosity grades and he told me using 5w-40 Rotella or the 15w-40 Rotella (synthetic or otherwise) is fine for where I live (central Virginia).
Hope this helps......"

Again. Ask your dealer or email Kubota for up to date information.

I just saw it yesterday in my local Bristol CT Walmart. To be honest, it was the first time I saw it. Previously I was buying the 1 qt containers at AutoZone. I do not have a picture of the container but I will try and get one with my cell camera the next time I am in there.

The only container I am aware of, other than the quart, is the 1 Gallon.... NEVER a 5 Gallon in Mobil 1 Turbo diesel....
also the Turbo diesel is NOT packaged in 5 Quart jugs like the rest of the Mobil1 line. Just Quart and 1Gallon.

I would like to see if a 5GALLON, like you say you saw, had a better price break. like say just under One Hundred $... KennyV

I also use Mobil 1 Turbo Diesel Truck oil 5W-40 and haven't had any problems. I like Mobil 1 because it's a true synthetic oil, Shell Rotella is not.

Oh gosh, the whole definition thing of "true" synthetic is too much a headache for me. I know there are like 3 or 4 categories of base stock, molecules, blah blah blah. Seriously, a major headache. OK, I'm done now.

Welcome to the world of synthetics...a nightmare at the best of times!

One day I saw the "discussion" on Grizzly and Rhino forum with claims of the synthetic Amsoil curing seized engines.

I use what the dealer recommends; can't change my own anymore anyway.

Well, estate tractor guys here way, way overthink all this anyhow, imho. Don't want start any flames burning, but golly by golly.

OTR trucks often go a MILLION miles on dino. How many hours do you suppose that is?

Big Cats and dozers often have 20,000 to 25,000 hours on them, again, with relatively plain old dino.

I like a good syth and a good additive package as well as the next guy, and I fully appreciate pride of ownership. But sometimes we scut/cut owners with our little diesels are just trying for a Geek-dom zip code.

Agree, my dad was a truck driver all his life; OTR and construction, my father in law owned a bulk distributorship for a major oil company with his own tankers and delivery trucks. A million miles was expected. Neither used synthetics.

I can't say that under some circumstances that synthetic is not better; just haven't seen it in normal use.

The difference is in the numbers and numbers.

Example the Flash point for cheap oil could be as low as 380 degrees and the pout point of only +15 degrees

While a good synthetic oil has a flash point of 527 degrees and a pour point of -92 degrees.

If better flash point and better pour points don't matter put in the cheapie oil, and do it more ofter. Synthetics offer real advantages when your engine is very cold and when your engine is very hot.

Since about 75% of all the wear on your engine happens in the first five minutes after you start it up, synthetics offer an advantage in significantly reducing engine wear.

Granted those big rigs might have gone a million miles but an average automobile engine is turned on and off dozens of times in only a few hundred miles, while the big rig might go thousands of miles and not be turned off once. Secondly you have hot diesel engines which are a good thing for engine oil, while a passenger car often times never gets hot enough to burn off and water in the oil from condensation.

So to compare an over the road truck with a passenger car is unfair.

For me the top ones are Rotella T Synthetic , Mobil 1 Delvac, and my favorite is the Red Line Diesel.

First, no one, I believe, was comparing anything to a passenger car.

With that out of the way, the discussion here was not an ANTI- Synthetic oil tone at all. Not a bit!! Due respect was paid to Synths. My little, bitty rant was merely to react when someone posts 1.) "Rotella T Synthetic isn't a true synthetic." it elicits in me, at least, the biggest "I don't care to go there" response, complete with glazed eyes.

Second, just to say that dino oil isn't BAD oil just because it's dino. That's all that was being said here. The examples of the OTRs was merely giving proper respect.

Finally, the OP's original question has long been answered, so if this is now a whole synthetic oil debate that is brewing, I will politely excuse myself.

Peace,
